A Node.js testing toolkit. You get the same test case library, assertion
library, etc. This is also great for hybrid browser and Node.js code. Write
your test case with Buster.JS and run it both in Node.js and in a real browser.

Flexible. There’s a public API for almost everything. You
can write reporters for customizing the output
of buster test (we already have xUnit XML, traditional dots,
specification, tap, TeamCity and more), write extensions that wrap other
testing frameworks (we already have buster-jstestdriver), add your own
testing syntax (we ship with xUnit and BDD), and much more. Again, the overview
lists many of these things.

Written by you. We believe in open development, and already
have a dozen or so contributors beyond the core authors of Buster.JS, August
Lilleaas and Christian Johansen. All development happens in public in the
issue tracker and the
busterjs-dev mailing list. We
welcome your opinion.

A set of reusable libraries. For example, ramp is
our generic browser automation library that lets you successively load webpages
into browsers and send data to and from them. It is completely reusable and has
no knowledge of Buster.JS tests, or tests at all for that matter.

The future. We have big plans for buster in the months and years to come. For
example, we’ll add the ability to run your browser tests directly on
BrowserStack. In development you can still
capture a local browser, JsTestDriver style. But instead of setting up your own
CI server with a bazillion browsers, pay BrowserStack to do the job for you.
Other plans we have is to have a stateful test runner that only runs the
previously failed tests, test breakpoints that drops you into a live REPL in
all the captured browsers when a test fails, and much much more.
